Abstract: 217,278. Lifford, J., Rowland, A. H., and Wood, E. H. A. March 5, 1923. Piano-players; exhausting air; expression-controlling; actions; winding-mechanism. - A selfcontained player adapted to be placed over a pianoforte keyboard comprises pneumatics and valves connected to a conduit-pipe of small crosssection, piston and cylinder suction-pumps actuated by a hand-crank which also drives the tune-sheet, and a tension-regulating valve controlling the admission of air against the action of a spring under hand-control. The apparatus, shown in plan in Fig. 1, is contained in a casing adjusted by screws 57, 58 over the keyboard. The metal valve-units 1 are supported, on either side of the conduit 100, by their flexible connections therewith. The striker-pneumatics 12 are covered with Egyptian cotton fabric and then doped with several coats of masticated rubber, to prevent leakage and to obviate the use of springs. The tension-regulating means comprise a valve 39, Fig. 5, admitting atmosphere to the system from a chamber 38a, an adjustable spring 42, whose action is variable for expression by a hand-operated wedge 43, tending to close the valve. Accentuation of the treble or bass from the tune-sheet is brought into operation by rotating a plug-valve 28, Fig. 9, admitting air at valveunits 35 to the underside of diaphragms controlling spring-pressed valves, in casings 18. A valve which is thus partially closed is opened fully on passage of an accenting-aperture over the trackerbar. The suction-pumps 44 are connected directly without a wind-chest to the port 48 of the accentor-devices, and their pistons are operated by a crank-handle 47. The tune-sheet is driven at one of two speeds, determined by a lever 62, by gearing also actuated by the handle 47. The tune-sheet is re-wound by another crank-handle 56. An electromotor may be also used to drive the apparatus. According to the Provisional Specification the pneumatics when below the keys are connected thereto by tapes.

Title: Coiling machine
Inventor: HAGENDORF WILLY
IPC: B21C47/04
Filed: 1966-02-15
Abstract: 1,134,210. Winding and reeling. SCHWERMASCHINENBAU ERNST THALMANN VEB. 15 Feb., 1966, No. 6601/66. Heading B3E. [Also in Division D1] Apparatus for coiling rod comprises a laying device to lay the rod in a rotated coiling device as the laying device is reciprocated vertically, the speed of the motor or motors driving the laying and coiling devices being reduced at the end of each movement of the laying device to compensate for the increased diameter of the coil being wound. Rod is directed by a laying tube 1 first into the space between an inner circle of coiling arms 11, upstanding from a coiler bottom 18 rotated by a motor 19, and an outer circle of catchpins 13 also upstanding from the coiler bottom 18, the space also being defined by a coiler support plate 12 above the bottom 18 and a cover 14 swung upwards by ram 15 partly to cover the circle of catchpins 13. After the first few turns have been laid in the said space, the cover 14 is pivoted out of the way and the plate 12 is raised above the catchpins 13. Coiling continues with the laying tube 1 moved upwardly, guided by a curved segment 9, about its pivot 4 by a drum cam 5 driven by a motor 6, so that a single layer coil is formed on the arms 11. When the tube 1 reaches its upper point a signal is sent to the motors 6, 19 to change their speeds, as programmed, to suit the new layer diameter. The tube 1 then descends under control of the cam 5. The change of speed is effected at each lower and upper point in the travel of the tube 1. When the end of the rod to be coiled is reached a signal switches off the motor 19, through a time switch a brake is applied to stop the coiling device and the tube 1 is stopped at its lowest point. A lifting device 24 then raises the coil which is pushed on to a conveyer by means 10. Cooling air may be blown on to the coil during cooling. In another embodiment, Fig. 2 (not shown), the movement of the tube 1 is effected by an hydraulic cylinder supplied by a pump driven from the motor 19 driving the coiling device.

Patent GB-785013-A (GB)
Title: Acylated dl-proline salts and their use in obtaining d-and l-prolines separately
Filed: 1955-03-08
Abstract: The invention comprises the salt of N-3,5-dinitrobenzyl - L - proline with D - (-) - threo-1 - p - nitrophenyl - 2 - amino propane - 1,3-diol and the salt of N-3,5-dinitrobenzoyl-D-proline with L - (+) - threo - 1 - p - nitrophenyl-2 - amino propane - 1,3 - diol and the use of these salts and the corresponding enantiomorphs (enantiomorphic salts) in obtaining separately D- and L-proline.  The salts are obtained by reacting L-(+)- or D-(-)-threo-1-p-nitro phenyl-2-amino propane-1,3-diol as resolution agent with N-3,5-dinitro benzoyl-DL-proline in an inert solvent in which only one of the two enantiomorphs gives a salt with the resolution agent, which is sparingly soluble in the solvent and separating the salts of the two enantiomorphs by means of the difference in their solubilities; the separated salts may be decomposed by treatment with a base followed by acidification to yield the dinitrobenzoyl D-and L-prolines which are saponified separately to D- and L-prolines.  The inert solvent may be water or preferably an aliphatic alcohol, e.g. ethanol.  The D-form of the resolution agent forms a sparingly soluble salt with only the N-3,5 - dinitro benzoyl - L - proline and the L-form of the resolution agents gives a sparingly soluble salt with the N-3,5-dinitrobenzoyl-D-proline, the other enantiomorphic salts formed being retained in solution.  The method may be used in the resolution of DL-proline, the N-3,5-dinitrobenzoyl DL-proline being obtained by direct acylation of DL-proline or by reacting 3,5-dinitrobenzoyl chloride with an ester or like functional derivative of DL-proline and then regenerating the N-acylated amino acid.  The resolution salt of the acylated L-proline may be converted to the free dinitrobenzoyl-L-proline or to L-proline, racemised and then returned to the resolution system.  In this manner, naturally occurring L-proline may be substantially completely converted to D-proline; the reverse procedure may also be followed with naturally occurring D-proline.  In examples: (1) N - 3,5 - dinitrobenzoyl - DL - proline is dissolved in water and the resolution agent in L-form is added; after stirring at 40 DEG  C., the precipitated salt is filtered off and decomposed by aqueous caustic soda, the liberated resolution agent is removed, the aqueous residue is acidified and the resulting acylated D-proline is recovered, hydrolysed with aqueous HCl and D-proline is obtained from the hydrolysate; the filtrate remaining after removal of the resolved salt of the acylated D-proline contains the salt of the L-resolution agent with the acylated L-proline and is treated as above to recover crude acylated L-proline which is then hydrolysed to L-proline; (2) the crude acylated L-proline obtained as in (1) is treated in water with the D-form of the resolution agent whereby the salt of the D-resolution agent with acylated L-proline is recovered and treated as above to give a purer L-proline.  Specification 745,097 is referred to.
